Captcha - ReCaptcha not displayed in Registration

I established an account and obtained the public and private 'keys', then entered them in the appropriate fields in the Captcha Plugin. I then set the User Options to "Captcha - ReCaptcha" and saved / refreshed the browser.

Captcha does not appear on the Registration Menuer page, yet when you press the "Resister" button with all of the other required fields filled-in properly, you get the alarm:

"WARNING: Empty solution not allowed."

This makes me believe that the Captcha Plugin is working, for you didn't answer the Captcha 'question' (even though you cannot see the Captcha module), the system thinks that you answered that question with an empty field (that is not allowed) and kicks you out. Am I correct in my analysis, and what do I need to check or do to fix this problem? I don't think that I've missed anything, but the system is telling me otherwise.

Thanks in advance for any help.

Try to get help for that on joomla forum that is not our area. See this:

Thanks for the help. I thought this may be a template problem rather than a K2 problem. Thanks again.
